You are effective at fighting with two weapons more-so than one.
Prerequisite(s): Dexterity 2+
Benefit(s): You increase your effectiveness while fighting with two weapons or double weapons, reducing your attack by less (beyond the typical -10 and -5). Fighting with two weapons can be done with unarmed strikes as well, but only with dual weapon mastery as a feat. While wielding two weapons you gain a Dodge bonus to your Reflex Defense, this bonus starts at +1 for Rank 1, +2 for Rank 2, and +3 for Rank 3.
Special: This feat can be taken up to 2 additional times, each time decreasing the reduction to dual weapon fighting.
This feat can also apply to 3 or more weapons although the penalty is increased by -3 for each additional attack beyond the second.
